We're going to give a breakout session that goes into more depth on Wednesday @ 4:35pm. IO244.

Some quick details: It's a bit of a split between what GKE runs and what the customer runs. Alpha runs on vSphere 6.5 and we're packing up a Google-hardened OS in much the same way we package GKE for GCP. A lot of the integrations for things like networking and storage will be coming from partners. We'll also have remote mgmt capabilities so we can manage the cluster's control plane in much the same way our SREs do for GKE.
